Milliliters (mL) and fluid ounces (fl oz) are both units used to measure volume, but they come from different measurement systems. You’ll often need to switch between them in the kitchen, the lab, and even everyday life.
So, exactly how many ounces are in 75 mL? This article will define the terms, give you the conversion formula, and, of course, provide the answer!
Milliliters and fluid ounces defined
Before we get to the math, let’s clarify what we’re talking about.
What is a milliliter (mL)?
A milliliter is a metric unit of volume that’s equal to one cubic centimeter (cc). Think of it as one one-thousandth of a liter.
Scientists and medical professionals often use milliliters to measure liquids.
What is a fluid ounce (fl oz)?
A fluid ounce is a unit of volume in the Imperial and US Customary systems. But here’s a twist: there are different kinds of fluid ounces, including US and UK fluid ounces.
- 1 US fluid ounce = approximately 29.5735 milliliters
- 1 UK fluid ounce = approximately 28.4131 milliliters
For this article, when we say “fluid ounces,” we’re talking about US fluid ounces.
The Conversion Formula
To convert from milliliters to US fluid ounces, you can use the following formula:
US fl oz = mL ÷ 29.5735296
Or, if you prefer multiplication:
US fl oz = mL 0.03381402265
These formulas are based on the relationship between the metric system and the US customary units. To make sure you get an accurate result, you must use the correct conversion factor.
Converting 75 mL to Fluid Ounces: Step-by-Step
Let’s convert 75 mL into U.S. fluid ounces.
- We’ll use the formula: US fl oz = mL ÷ 29.5735296
- Now, let’s do the math: US fl oz = 75 mL ÷ 29.5735296
- The result is: US fl oz = 2.53605 (roughly)
So, 75 mL is about 2.536 US fluid ounces.
For most purposes, rounding that to 2.54 ounces is fine.
Conversion Chart: Milliliters to Fluid Ounces (Around 75 mL)
Sometimes you don’t need a super-precise conversion, but it helps to know roughly how the fluid ounce value changes as the milliliter value shifts. Here’s a quick reference for values near 75 mL:
- 74.9 mL = 2.5326 oz (approximate)
- 75.0 mL = 2.5361 oz (approximate)
- 75.1 mL = 2.5395 oz (approximate)
- 75.2 mL = 2.5430 oz (approximate)
Keep in mind that the level of precision you need depends on what you’re doing. Eyeballing it is fine for cooking, but you’ll need to be more exact for scientific work.

Important Considerations: Weight vs. Volume
It’s vital to remember that fluid ounces (volume) are different from ounces (weight). We’ve been talking about fluid ounces so far. If you want to convert milliliters to ounces by weight, you need to know the density of the substance you’re measuring.
Here’s the formula: weight (oz) = volume (mL) density (oz/mL).
This is especially important in cooking. For dry ingredients, measuring by weight is much more accurate than measuring by volume, because different substances have different densities. For example, a milliliter of water will weigh a different amount than a milliliter of flour or sugar.
Just so you know, 1 mL of water is about equal to 1 gram, but this doesn’t hold true for other substances.
Key Takeaways
Converting milliliters (mL) to fluid ounces (fl oz) is straightforward. Remember the key conversion factor: 1 mL is approximately equal to 0.033814 fluid ounces. So, to convert, simply multiply the number of milliliters by 0.033814.
Applying this formula, we find that 75 mL is approximately equal to 2.536 fluid ounces.
Keep in mind that fluid ounces measure volume, while ounces (without the “fluid” prefix) measure weight. They are not the same!
